Need help finding 800VAC output transformer for KGSS

post #1 of 6
Thread Starter 
If you have a look at the headwize writeup on Kevin Gilmore's solid state electrostatic amplifier, it needs a 800VAC transformer, that i have been completely unable to locate. I have found every other part, but I cant find this one. As loath as i am to start a thread over something like this, i really cant seem to find anything, and i need your help! Please!
Thanks\Greg

He gives the transformer as a Thordarson 24R22U with an Allied Electronics stock number. They don't seem to carry i anymore, so you could either contact the company directly, or get the specs from it and try others such as Victoria Magnetics, etc. (do a search on transformers here as there is another vendor that people have been getting more or less custom-spec'd transformers for Dynahi's, etc. from but I can't recall who it is). This is a power transformer, not an output transformer btw.

I know about the allied part number, and how he doesnt carry it, and that it is a power transformer. I will check out victoria magnetics, thank you for that.

Actually, i found the exact hammond i need. Obscure reference on some guide led me to the HAMMOND 273BX, which i managed to find a version of in my mouser catalog at 400-0-400 on the secondary output, with 200ma of current. Perfect! Now if only it didnt cost $140...meh, its worth it (by the way, having a mouser catalog is insanely useful. I know its an advertising technique, but i dont really care)
